Ultra-high Capacity Transmission with Few-mode Silica and Hollow-core Photonic Bandgap Fibers

Abstract

Abstract:We review the capacity records achieved using mode-division multiplexing in few-mode fiber and hollow-core photonic bandgap fibers. Currently the MDM-capacity record for both fiber types is 73.7 Tb/s, whereas per wavelength 960 Gb/s is achieved.

“…Few mode fiber (FMF) transmission is currently subject to intense research of future mode division multiplexing (MDM) communication system to increase the transmission capacity and avoid the foreseen "capacity crunch" [1][2][3] . One such MDM method, orbital angular moment (OAM) multiplexing has seen its potential use in optical communications to enhance the transmission capacity and spectral efficiency in FMF transmission.…”

Characterization of Rayleigh backscattering arising in various two-mode fibers

“…Recently, few-mode fiber (FMF) has been widely investigated to avoid the capacity crunch of single mode fiber (SMF) [10][11][12][13]. Mode division multiplexing (MDM) transmission using the FMF can effectively increase the capacity of SMF by N times through the utilization of parallel spatial modes as independent information channels [14,15]. As a new application, FMF is proposed for passive optical networks (PON) due to its potential to maximize the loss budget and the number of optical network units (ONUs).…”
